Vedclass · Answer

(A) $1$. Molar mass of $A$ is $121 \ g/mol$. Benzamide $(C_6H_5CONH_2)$ has a molar mass of $121 \ g/mol$ and contains nitrogen,thus giving a positive Lassaigne's test.$2$. The reaction of benzamide with $NaOH$ followed by $H_3O^+$ is an alkaline hydrolysis,which converts the amide group $(-CONH_2)$ into a carboxylic acid group $(-COOH)$,yielding benzoic acid $(B)$.$3$. Benzoic acid $(B)$ reacts with $NaHCO_3$ to release $CO_2$ gas,causing effervescence.$4$. The reaction of benzoic acid $(B)$ with ethanol $(EtOH)$ in the presence of $H_2SO_4$ and heat is an esterification reaction,which produces ethyl benzoate $(C)$,characterized by a fruity smell.
